Researchers Develop Holographic Display Powered by Tiny Pistons

By

Researchers have developed a ” holographic display built with standard semiconductor processes; Francesco Pessolano, manager of Imec’s NVision program, suspects detailed 3-D video displays can be made by moving reflective microelectromechanical systems (MEMS) structures up and down like microscopic pistons.” Video demonstration after the break.

After topping that entire grid with a fine layer of reflective aluminum, they shine laser light onto the pixels at an angle, and the varying ways this light diffracts from the uneven surface they’ve created cause the light to interfere with itself both constructively and destructively. Long story short, if the pixels have been precisely etched a 3-D holographic still image emerges.

Meteor Shower (Quadrantids) Live Video Stream Now Online, Peaks Tonight

By

What better way to start 2012 than with a meteor shower, the Quadrantids to be exact. Simply put, “the best place to view the meteors live is the East Coast of North America, since the Quadrantids is best seen from the Northern Hemisphere and it happens to be the middle of the night in that region when they’re due to hit.” Or, you can continue reading to see a live video stream.

No, you don’t, but a good pair of binoculars could enhance the show. Also, get your camera ready on a tripod. To get the above, Brian Emfinger used a Canon T1i camera with 8mm Fisheye lens at F3.5 and ISO3200, exposing for 30 seconds.

Weird and Geeky Periodic Tables

By

Technically speaking, a periodic table is essentially “a tabular display of the chemical elements, organized on a basis of their properties. Elements are presented in increasing atomic number; while rectangular in general outline, gaps are included in the rows or periods to keep elements with similar properties together, such as the halogens and the noble gases, in columns or groups, forming distinct rectangular areas or blocks.” Continue reading to see some of the weirdest and geekiest designs.

Mercury, also known as quicksilver and hydrargyrum, is found in deposits throughout the world mostly as cinnabar, which is highly toxic if ingested or inhaled. It has a boiling point of 356.73C and a freezing point of -38.83C. Continue reading to see five of the weirdest mercury experiments.

Shroud of Turin Created with Flash of Supernatural Light, Claim Scientists

By

According to Italian scientists, after spending two-years trying to replicate the shroud’s markings, they “concluded only something akin to ultraviolet lasers – far beyond the capability of medieval forgers – could have created them; this has led to fresh suggestions that the imprint was indeed created by a huge burst of energy accompanying the Resurrection of Christ.” Continue reading for a video.

‘The results show a short and intense burst of UV directional radiation can color a linen cloth so as to reproduce many of the peculiar characteristics of the body image on the Shroud of Turin,’ the scientists said.

It’s something humans can’t live without, and can be found in three states: liquid, solid, and invisible (vapor in air). What is it you ask? Water of course. On Earth, water “moves continually through the hydrological cycle of evaporation and transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.” Continue reading to see seven ultra weird things you can do with the chemical substance.

For those who have taken basic science courses at school, liquid nitrogen is something that many students have experimented with. Now, we’ve rounded up seven of the weirdest experiments that you’ve probably never tried before. In technical terms, “at atmospheric pressure, liquid nitrogen boils at 77K (-196C; -321F) and is a cryogenic fluid which can cause rapid freezing on contact with living tissue, which may lead to frostbite.” Continue reading to see them all.
